Japes, you need take another break so the rest of our fish look good for a minute! :j/k:
They are beautiful. I hope my orange heads turn out even close to yours eventually...

Cheers for the lovely comments guys.
On their tank I'm using a 4' 2x54W T5HO setup with a standard 10000K and an 8500K Sylvania Grolux (Blue-Red Tube)
They're in with a large shoal of Lemon Tetra, small shoal of Golden Pencilfish, and the species that you think look like Black Neon Tetra are actually Blackline Penguin or Hockeystick Tetra.
I guarantee you do, they're just labelled as the Tapajos variant. To keep it short, there's a fair amount of drama surrounding the labelling of the Araguaia variant by Thomas Weidner in his South American Eartheaters book as Heiko Bleher is hugely confident that an Orange Head complex species doesn't exist in the Rio Araguaia. This fits with the description in the book stating that exact catch locations were not recorded or something similiar.
The two complexes are believed to exist in the Rio Negro and Rio Tapajos. A co-developer ozarowana on http://eartheaters.qldaf.com might be onto a method of identification, but it's dependant on a lot of variables, and we're unsure of how accurate it is due to the lack of knowledge with possible interbreeding between the two variants (whether this can actually occur we're not sure, but we imagine it can)
Here's his lovely Geophagus sp. "Tapajos Orange Head" pair.
Note the orange stripe that runs from the rear base of the dorsal fin that runs along the top of the caudal peduncle.
For comparison, here's a shot of one of my fully coloured males tail with no stripe present.
Not even a slight hint of any orange or red, but we're still testing the theory.
